Economies of Scale

Have you ever thought of how milk companies can sell small sachets of milk at so low prices across the world? Or how can Ikea sell flat-pack furniture at what seems impossibly low prices? Or how can a large retailer like Walmart maintain so low prices? The answer lies in the concept of economies of scale. The above mentioned companies are just some examples of many of the companies performing and using the concept of economies of scale. Other big players on the market, well-known for practicing it are Procter & Gamble, Exxon Mobile Corporation, United Parcel Service, Fedex, Intel Corporation and others.

The concept itself of “economies of scale” is quite easy to explain and understand and it involves the cost advantage that occurs when we increase production of a product. The idea is based on the inverse relationship between the quantity produced and per unit fixed costs. Therefore, the greater the quantity produced, the lower the fixed costs as these costs are shared over a larger number of products. At the same time, many variable costs can be reduced due to operational efficiencies and synergies.

Lets understand Economies of scale with an example.

A product X has a fixed cost of 10000 dollars for production of 100 units. Thus, the cost of production is 100 dollar per unit. However, now the factory increases production of 1000 units from the same factory. At such time, the fixed cost is the same i.e 10000 dollars. Thus, when you increase production to 1000 units, the per unit fixed cost is just 10 dollars. Thus, because of increase in manufacturing capacity or total units produced, economies of scale sets in and the cost of the product goes down.

We can speak about economies of scale from different perspective. One of them consists in the two types of economies of scale, either internal, when it is arising from within the company or external, when it is arising from external factors such as industrial size.
Another perspective, would divide the economies of scale in four categories such as:

Technical economies of scale

Specialization of the workforce (leading to economies of scale)

Marketing economies of scale

Financial economies of scale

Let’s take the first category, the technical economies of scale. To produce energy, the energy company from Tanzania, Tanesco, had to invest in a huge network of energy poles stretching through the country. The fixed cost of this investment was very high. However, since they distribute energy to more than 3 millions of households, it brings the average cost down.

For the second category mentioned above, i.e specialization of the work force, the most suitable example would be in the production of cars or different kinds of electronic equipment. When we have to build a car, there are a number of employees involved in the process. If for each of the processes we split the employees as they would specialize in the production of certain parts of the car, therefore, there will be an increased level of efficiency in the production process and a decrease in the need of more employees. Same ways, automation of industries increases the fixed cost, but by increasing production, decreases the per unit cost.

Financial economies of scale might be explained through a different example. If we were to consider that when a consultancy company is working with a biscuit company to sell them on a foreign market, it is important to see how many packages of biscuits can fit into a container. This is also known as the container principle, meaning that, as more products can fit into a container, lesses costs are going to be involved in distribution.

The marketing example of economies of scale is bulk buying. When people go to hypermarkets to buy in bulk, it will be cheaper than buying from smaller shops in smaller quantities.

The economies of scale is not only a cost advantage but can be considered as an entry barrier for new competitors, as they will have to sacrifice profitability levels to stay on the market. By focusing on this concept, companies can manage to improve logistics and price advantages while attracting more customers.
